The present invention relates to a carpet that has the function of preventing the growth and proliferation of bacteria and fungi (hereinafter referred to as having antibacterial properties). More specifically, tufted carpet, needle punch carpet, Wilton carpet, etc.
The present invention relates to a carpet that is composed of adhesive parts and that has persistent antibacterial properties. BACKGROUND ART In recent years, with the spread of carpets, the proportion of carpets installed in homes, public buildings, etc. is increasing. In general, carpets are laid on floors where dirt and other dirt may fall,
This has been a field of concern from a sanitary standpoint, as it is used by stepping on it and does not need to be cleaned frequently. Particularly in environments where the spread of air conditioning maintains a comfortable temperature for bacteria throughout the year, the chances of infection and multiplication of bacteria and fungi based on carpet installation are significantly increased.
Hygiene issues in carpets have become increasingly important in recent years. In other words, it has been recognized that antibacterial treatment is necessary for carpets in order to prevent carpet-borne diseases, reinfection of diseases, and the generation of bad odors. Under these circumstances, carpets with antibacterial properties have been proposed, and drugs (hereinafter referred to as antibacterial agents) have the function of preventing the growth and proliferation of bacteria and fungi when they come into contact with the fibers of the carpet. It is known that products with antibacterial properties can be made by impregnating or applying them. By the way, conventional antibacterial carpets are made by impregnating or coating the pile yarn itself with an antibacterial agent, and although it has a certain antibacterial effect, it is not always satisfactory, and this antibacterial property does not last for a long time. In use, it was less effective. Furthermore, since the area to which the antibacterial agent is applied is the pile part, it comes into direct contact with the human body, so there is a risk of inducing damage to the human body such as skin damage. In view of the current situation, the inventors of the present invention have conducted extensive research into the mechanism of expression of the antibacterial effect in order to provide a carpet that has excellent antibacterial effects and has sustained antibacterial properties. After discovering that the gradual oozing of an antibacterial agent from the carpet has a very large effect on the antibacterial effect, they conducted further research and finally arrived at the present invention. That is, the gist of the present invention resides in a carpet having a pile fixing adhesive layer, in which the adhesive contains an antibacterial agent. The carpet according to the present invention utilizes the structure of the carpet, which is a composite material unlike ordinary fabrics, and contains an antibacterial agent in the backing adhesive, thereby making the carpet permanently antibacterial. If a carpet containing an antibacterial agent is infected with, for example, staphylococcus, the cocci will no longer proliferate and will die after a certain period of time. A feature of the carpet of the present invention is that by incorporating an antibacterial agent into the adhesive layer, the antibacterial agent gradually oozes out, and as a result, it has an antibacterial effect both at the initial stage and during long-term use. Furthermore, while conventional carpets are antibacterial carpets in which the pile yarn itself is impregnated or coated with an antibacterial agent, the carpet of the present invention has no antibacterial agent exposed on the surface, so it is extremely safe for the human body. In addition, impregnating or applying an antibacterial agent to the pile threads that make up the appearance of the carpet may discolor the surface of the carpet or impair the feel of the carpet, but the carpet according to the present invention does not contain the antibacterial agent. Since it is not directly attached to the pile yarn, these concerns are completely eliminated. As described above, the carpet of the present invention is a carpet that solves the conventional problems by containing an antibacterial agent in the adhesive, has a sustained (long-term) antibacterial property, and is resistant to human body damage. It has remarkable effects on safety, appearance, texture, etc. The carpet of the present invention is particularly useful for carpets used by a large number of people, ie, carpets used in hotels, dormitories, nursing homes, hospitals, and the like. Hereinafter, the configuration, embodiments, and effects of the present invention will be explained in detail. In the present invention, the carpet pile fibers include synthetic fibers such as acrylic fibers, nylon fibers, polyester fibers and polypropylene fibers, recycled fibers such as rayon and Kyupra, and natural fibers such as cotton and wool. The base fabric may be made of synthetic fibers, natural fibers, or regenerated fibers like pile fibers, but it is preferable to have a structure with voids all over the surface, such as woven fabrics or nonwoven fabrics with textures. Fabrics using tape yarn made by shredding polypropylene film commonly used in tufted carpets, interwoven fabrics of spun yarn and tape, spun yarn fabrics such as synthetic fiber cloth, blended fabric, cotton cloth, jute Cloth and the like are preferred as the base fabric for the carpet of the present invention. The adhesive used in the present invention may be any rubber-based or vinyl-based adhesive used in carpets, but styrene-butadiene latex, which is often used in tufted carpets, exhibits good effects. These latexes are used as compounds, but latexes that do not contain any filler components such as calcium carbonate or clay are not preferred because they prevent the antibacterial agent from leaching out after solidification. According to experiments conducted by the inventors, an adhesive containing at least 2 to 10% by weight of a filler component based on the adhesive base material component is preferred. The amount of adhesive to be applied is preferably within a commonly used range, and should be used in an amount that provides a sufficient adhesive effect in view of the practical functionality of the carpet. As the antibacterial agent in the present invention, benzalkonium chloride, chlorhexidine, etc. are used, but any antibacterial agent used as an antibacterial agent for textiles such as clothing can be used. The amount of antibacterial agent added in the carpet of the present invention is
Although the boundary is not clear as to the appropriate amount of adhesion when used on the conventional pile fiber itself, it is preferably twice or more.
For example, when using chlorhexidine (purity 20%), when the appropriate amount of adhesion to the conventional pile fiber itself is 0.5% (apparent) of the weight of the pile fiber,
In the carpet according to the present invention, the boundary is not clear, but it is preferably added in an amount of 1.0% by weight or more based on the weight of the pile fibers. In other words, in the case of a carpet with a pile fiber weight of 1 kg per square meter and an adhesive solid component of 1 kg, the antibacterial agent is applied to the adhesive solid component.
It is preferable to add 1.0% by weight or more, and when the pile fiber weight is 0.5 kg and the adhesive solid component is 1 kg, it is preferable to add 0.5% by weight or more of the antibacterial agent to the adhesive solid component. In this way, the approximate amount of addition should be determined based on the weight of the pile fibers, but it should be changed as appropriate depending on the form, density, and pile height of the pile fibers.According to the experiments conducted by the present inventors, When the antimicrobial resistance increases, favorable results are obtained by increasing the amount of antibacterial agent added. In the present invention, it is preferable to add the antibacterial agent to the adhesive to disperse it as uniformly as possible. For example, in the case of a styrene-butadiene latex compound, the main components are raw latex, filler, and dilution water. It is preferable to add a pre-calculated amount of antibacterial agent to water, mix and disperse completely, and then stir and mix and disperse the raw latex while diluting it. The adhesive containing the antibacterial agent is applied to the carpet greige and hardened using a commonly used method. For example, in the case of a styrene-butadiene-based latex compound, it is applied using the normal lit roller method.
Dry at a temperature of about 120-160℃. The present invention will be explained below with reference to Examples. All "parts" and "%" described in the examples are parts by weight,
Indicates weight %. Example 1 Using a base fabric made of polypropylene tape yarn as the primary base fabric, acrylic fibers were made by the tufting method.
We made carpet greige with 1 kg of cut pile per square meter using 100% pile yarn and loop pile of 1 kg per square meter with 100% nylon fiber pile yarn, and applied backing adhesive to fix the pile of this carpet greige. For this purpose, the adhesive components of the latex compound shown below were blended. Carboxylated SBR (50% pure) 200 parts Nonionic activator 0.45 parts Antifoaming agent 0.09 parts Calcium pyrophosphate 1 part Calcium carbonate 250 parts Thickener 2 parts The solid content of this adhesive component is approximately 350 parts. A benzalkonium chloride antibacterial agent was added to 180 parts of water for dilution and stirred well to disperse it uniformly.The adhesive components were then diluted and mixed with thorough stirring to form an adhesive. The amount of benzalkonium chloride antibacterial agent added is 0%, 1%, and 2%, respectively, based on the solid content of the adhesive.
%, 4%, and 8%. The solid content of this adhesive is 1 kg per 1 square meter.
The mixture was applied to the back side of the carpet greige, and a jute cloth was further applied and heated at 140° C. for 6 minutes to evaporate water and form a carpet. For comparison, the same antibacterial agent as in Example 1 was sprayed on the pile of a carpet in which no antibacterial agent was added to the adhesive, and the amount
2% was deposited (comparative example). Antibacterial efficacy tests were conducted on these carpets. In this test method, a circular sample carpet with a diameter of 20 mm was placed in close contact with a broth agar plate medium inoculated with two types of bacteria, Staphylococcus and Escherichia coli, and cultured at 37°C for 24 hours. The growth inhibition effect of the antibacterial agent on the bacteria was measured by measuring the width of the growth inhibition zone (halo) that appeared around the sample, and expressed as the average value (unit: millimeters). Next, in order to see the persistence of the effect over time, Example 1
Next, these carpets were laid in the hallway on the first floor of an office building, and after being put into practical use for 6 months, a similar antibacterial efficacy test was conducted. The number of people who passed through the facility during the six-month period was 139,272. The above results are shown in Table 1. The results shown in Table 1 confirm the antibacterial properties of the carpet prepared by adding an antibacterial agent to the carpet adhesive, and confirm that the antibacterial activity is durable and long-lasting. On the other hand, carpets in which an antibacterial agent was applied to the pile by a spray method showed initial antibacterial properties, but showed little or no antibacterial properties after six months of use. In addition, it was found that in the initial stage, the amount of the former added was about twice the amount of the latter attached, and the same antibacterial effect was obtained. The carpet of the present invention obtained in Example 1 showed no problems at all in human skin damage tests, and was found to comply with the Act on Regulation of Household Products Containing Harmful Substances (Ministry of Health and Welfare Ordinance No. 40 promulgated in 1970, 1978). No harmful substances specified in the Ministry of Health and Welfare Ordinance No. 64 [hexachloroepoxyoctahydroendoexodimethanonaphthalintris(2,3-dibromopropyl)phosphate tris(1-aziridinyl)phosphine oxide] were detected and entered the human body. It was confirmed that the safety of the drug was extremely high. Furthermore, when compared with a carpet that did not use antibacterial agents, there was no change in texture or color difference on the carpet surface, and no discoloration or fading was observed in the light fastness test. On the other hand, the comparative example had some problems in the human skin damage test, with changes in the texture and slight discoloration of the carpet surface before and after spraying the antibacterial agent, and considerable discoloration and fading in the light fastness test. . Example 2 Using the same carpet greige and adhesive components as used in Example 1, chlorhexidine (20% pure) as an antibacterial agent was added and mixed using dilution water as in Example 1, and the following was done. A carpet was prepared in the same manner as in Example 1. The amount added is based on the solid content of the adhesive.
0%, 0.2%, 0.4%, 0.8%, and 1.6%. An antibacterial activity test was conducted on each of these carpets in the same manner as in Example 1. As shown in Table 2, the results confirmed the antibacterial properties of the carpet prepared by adding an antibacterial agent to the adhesive. Further, like Example 1, this carpet was highly safe for the human body, and there was no change in texture or discoloration of the carpet.
